If I use Aurora to play a unit onto an open battlefield at 7 points (after having already scored from the other battlefield this turn), do I score the second point and win immediately?

Ruling: Yes, you score and win immediately. If you conquered one battlefield and the second one is open, conquering it triggers scoring and victory.

Nuances:

• It doesn't matter that it's not end of turn; what matters is whether both conquests happened in the same turn
